Description

Technical Field

[0001] This invention relates to the field of coloring apparatus, specifically to a coloring apparatus for glass products and a coloring method thereof. Background Technology

[0002] Glass was discovered accidentally during the glazing of porcelain. Currently, most glass is made from a specific ratio of quartz sand, soda ash, feldspar, and limestone. Before manufacturing glass, workers melt the raw materials in a furnace into a slurry, then use machines to create various glass molds. Glass artisans can also shape the slurry into vessels of various forms, and by adding different materials, they can create glass products of different textures. To meet the needs of different groups, glass products are coated with various colors.

[0003] For example, patent document CN206666392U discloses a novel glass coloring device, including a storage cylinder with an inlet and a handle. A nozzle is fixed to the front end of the storage cylinder. Pins are located at the top and bottom of the storage cylinder near the nozzle, with rotating rods on the pins and straight pipes fixed to the rotating rods. Through holes are provided on both the nozzle and the straight pipe. A brush is fixed to the nozzle. A micro water pump is located at the bottom of the storage cylinder, and the micro water pump is connected to the storage cylinder, nozzle, and straight pipe via a conveying hose. Magnetic blocks are also fixed on both sides of the storage cylinder. The technical solution provided above can effectively overcome the defect of uneven glass coloring in the prior art.

[0004] However, the aforementioned patent documents still have the following shortcomings in practical application:

[0005] The process cannot achieve an automatic coloring effect on glass products, requiring manual operation of handheld devices to achieve the coloring work. The whole process is time-consuming and labor-intensive, with low coloring efficiency, and it is impossible to guarantee that the thickness of the coloring layer on the glass is consistent. Summary of the Invention

[0006] The purpose of this invention is to provide a glass product coloring apparatus and method to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A glass product coloring device includes a worktable, on which an automatic coloring component, a glass positioning component, and a drying component are provided;

The groove plate is provided with ventilation holes near the coloring cylinder. An electromagnetic valve is provided inside the air outlet nozzle.

[0013] This invention utilizes multiple distance sensors installed on the drying tube to record the tilt of the glass during the cleaning process. These sensors then control the brush to adjust the distance between the brush and the glass according to the tilt, thus preventing uneven coloring layer thickness caused by glass tilt. Simultaneously, the hot air volume of the drying tube is adjusted based on the glass tilt to avoid uneven coloring layer thickness due to excessive or insufficient drying force. Furthermore, the airflow is adjusted during the movement of the drying tube based on the distance sensor readings to prevent colorant sedimentation within the coloring cylinder, which could affect the coloring effect.

[0014] Preferably, a guide post is fixedly connected to the middle of the rear end face of the L-shaped plate, a fourth motor is fixedly connected to the middle of the rear end face of the grooved plate, the output end of the fourth motor is fixedly connected to a sliding rod through a pin, and the guide post is embedded in the sliding rod through a groove and slidably connected to it.

[0017] Preferably, the front and rear ends of the left side of the frame are slidably connected to a first slider via grooves, and the front and rear ends of the right side of the frame are slidably connected to a second slider via grooves. The upper ends of the first slider and the second slider are fixedly connected to a sliding rod, and the left and right sides of the sliding rod are fixedly connected to threaded blocks. The lower end of the threaded block is threadedly connected to a bidirectional threaded rod, and the left and right ends of the bidirectional threaded rod are rotatably connected to the first slider and the second slider, respectively.

[0019] Preferably, a worm gear is sleeved and fixedly connected to the right end of the bidirectional threaded rod, and a worm is rotatably connected to the right end of the second slider. The ends of the worms on the front and rear sides that are close to each other are respectively connected to a grooved cylinder and a protruding rod. The protruding rod is inserted into the grooved cylinder, and the worm and the worm gear mesh with each other.

[0020] Preferably, the left end of the first slider is rotatably connected to a connecting rod via a pin, and the end of the connecting rod away from the first slider is rotatably connected to a threaded slider via a pin. The middle part of the threaded slider is threadedly connected to a second threaded rod, and the lower end of the second threaded rod is rotatably connected to the frame.

[0021] Preferably, the lower end of the drying pipe is provided with an air outlet nozzle, and both the upper and lower sides of the right end face of the drying pipe are fixedly connected to sliding columns. The sliding columns are slidably connected to displacement columns, and the right end face of the sliding columns is fixedly connected to a rectangular block. The lower end of the displacement column is slidably connected to a second sliding groove plate, and the rear end face of the second sliding groove plate is fixedly connected to a third motor. The output end of the third motor is fixedly connected to a third threaded rod, which is threadedly connected to the displacement column. The lower end face of the second sliding groove plate is fixedly connected to the worktable. A spring is sleeved on the right end of the upper sliding column. The left end of the spring is fixedly connected to the displacement column, and the right end of the spring is fixedly connected to the rectangular block. The right side of the displacement column is rotatably connected to an eccentric block and a gear through a pin shaft. A rack is fixedly connected to the right side of the upper end face of the worktable, and the rack and gear mesh with each other.

[0022] A coloring method for a glass product coloring apparatus includes the following specific steps:

[0023] S1. According to the size of the glass product, the operator manually rotates the second threaded rod to drive the threaded slider to rise and fall. Under the action of the connecting rod, the first sliders on the front and rear sides slide in opposite directions at the same time, adjusting the distance between the first sliders. At the same time, the protrusion rod and the grooved cylinder slide relative to each other. Then, the operator manually rotates the handle of the front worm gear to make the worm wheel, grooved cylinder, and protrusion rod rotate, causing the bidirectional threaded rod to rotate, making the threaded blocks on the left and right sides move closer or further apart, so that the upper end of the suction cup just contacts the four corners of the glass product. Then, using the air pump, the suction cup can be used to adsorb and position the glass product.

[0024] S2. When it is time to start coloring the glass product, start the first motor to drive the first threaded rod to rotate, so that the L-shaped column moves left and right. Start the second motor to drive the fourth threaded rod to rotate, so that the groove plate moves back and forth, thereby adjusting the position of the brush. Then start the fourth motor to drive the sliding rod to rotate counterclockwise, so that the guide column moves from right to left. The L-shaped plate slides to the left on the lifting rod. The lifting rod rises and then falls on the groove plate, so that the brush moves along the groove trajectory of the groove plate and is immersed into the coloring cylinder for coloring. Then start the fourth motor to drive the sliding rod to rotate clockwise again, so that the brush leaves the coloring cylinder and moves downward, so that the brush contacts the glass product. The first motor and the second motor are used to move the brush to perform the coloring work.

[0025] S3. After coloring is completed, the operator can simultaneously start the third motor and the hot air blower. The hot air blower delivers hot air to the drying tube through the hot air pipe and blows it onto the glass products from the nozzle. With the forward and backward movement of the displacement column, the drying range in the front and back directions is expanded. At the same time, the eccentric block rotates continuously under the action of the gear. The eccentric block continuously squeezes the rectangular block, causing the sliding column to slide and return to its original position under the action of the spring, so that the drying tube moves left and right, expanding the drying range in the left and right directions until the glass products are dried.

[0026] S4. Finally, remove the glassware.

[0027] Compared with the prior art, the beneficial effects of the present invention are:

[0028] 1. In this invention, when it is necessary to start coloring glass products, the first motor is started to drive the first threaded rod to rotate, causing the L-shaped column to move left and right. The second motor is started to drive the fourth threaded rod to rotate, causing the grooved plate to move back and forth, thus adjusting the position of the brush. Then, the fourth motor is started to drive the sliding rod to rotate counterclockwise, causing the guide column to move from right to left. The L-shaped plate slides to the left on the lifting rod, and the lifting rod first rises and then falls on the grooved plate, so that the brush moves along the grooved trajectory of the grooved plate, immersing the brush into the coloring cylinder for coloring. Then, the fourth motor is started again to drive the sliding rod to rotate clockwise, causing the brush to leave the coloring cylinder and move downwards, so that the brush contacts the glass product. The first and second motors are used to move the brush and perform the coloring work, thus achieving an automatic coloring effect on the glass products, thereby eliminating the need for manual coloring, increasing efficiency, and reducing the likelihood of paint getting on the personnel.

[0029] 2. In this invention, based on the size of the glass product, the operator manually rotates the second threaded rod to raise and lower the threaded block. Under the action of the connecting rod, the first sliders on both the front and rear sides slide in opposite directions simultaneously, adjusting the distance between the first sliders. At the same time, the protruding rod and the grooved cylinder slide relative to each other. Then, the operator manually rotates the handle of the front worm gear to rotate the worm wheel, the grooved cylinder, and the protruding rod, causing the bidirectional threaded rod to rotate. This causes the threaded blocks on the left and right sides to move closer or further apart, so that the upper end of the suction cup contacts the four corners of the glass product. Then, using an air pump, the suction cup can adsorb and position the glass product, thus achieving a positioning effect for glass products of different sizes, thereby ensuring the stability of the glass product during the coloring process and preventing it from shifting.

[0030] 3. In this invention, after coloring is completed, personnel can simultaneously start the third motor and the hot air blower. The hot air blower delivers hot air to the drying tube through the hot air pipe and blows it onto the glass product from the nozzle. With the forward and backward movement of the displacement column, the drying range in the front and back directions is expanded. At the same time, under the action of the gear, the eccentric block rotates continuously, and the eccentric block continuously squeezes the rectangular block, causing the sliding column to slide and return to its original position under the action of the spring, causing the drying tube to move left and right, expanding the drying range in the left and right directions until the glass product is dried. This achieves an automatic and uniform drying effect on the colored glass product, making it easier for personnel to collect it quickly. Attached Figure Description

[0042] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. Several embodiments of the invention are illustrated in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

[0043] Example 1

[0044] Please see Figure 1-8 The present invention provides a technical solution:

[0045] A glass product coloring device includes a worktable 1, on which an automatic coloring component, a glass positioning component, and a drying component are provided;

[0046] The automatic coloring assembly includes a grooved plate 11. A lifting rod 14 is slidably connected to the left end of the grooved plate 11 via a groove. An L-shaped plate 13 is slidably connected to the lifting rod 14. A brush 12 is fixedly connected to the middle of the lower end face of the L-shaped plate 13. A coloring cylinder 16 is provided at the lower left end of the front end face of the grooved plate 11. An L-shaped column 5 is slidably connected to the upper end of the grooved plate 11 via a groove. A first sliding plate 2 is slidably connected to the lower end of the L-shaped column 5 via a groove. The lower end face of the first sliding plate 2 is fixedly connected to the worktable 1.

[0047] The glass positioning assembly includes a frame 17, the lower end of which is fixedly connected to the worktable 1;

[0048] The drying assembly includes a hot air blower 43, the upper end of which is fixedly connected to the workbench 1.

[0049] In this embodiment, as Figure 1 , Figure 2 , Figure 6 As shown, a guide post 41 is fixedly connected to the middle of the rear end face of the L-shaped plate 13, and a fourth motor 39 is fixedly connected to the middle of the rear end face of the grooved plate 11. The output end of the fourth motor 39 is fixedly connected to a sliding rod 15 via a pin. The guide post 41 is embedded in the sliding rod 15 through a groove and slidably connected to it. A second motor 6 is fixedly connected to the rear end face of the L-shaped column 5. A fourth threaded rod 42 is fixedly connected to the output end of the second motor 6. The fourth threaded rod 42 is threadedly connected to the grooved plate 11. A first motor 4 is fixedly connected to the left end face of the first sliding plate 2. A first threaded rod 3 is fixedly connected to the output end of the first motor 4. Both ends of the first threaded rod 3 are rotatably connected to the first sliding plate 2. The first threaded rod 3 is threadedly connected to the L-shaped column 5.

[0050] In use, when it is necessary to start coloring the glass product, start the first motor 4 to drive the first threaded rod 3 to rotate, causing the L-shaped column 5 to move left and right. Start the second motor 6 to drive the fourth threaded rod 42 to rotate, causing the grooved plate 11 to move back and forth, thus adjusting the position of the brush 12. Then start the fourth motor 39 to drive the sliding rod 15 to rotate counterclockwise, causing the guide column 41 to move from right to left. The L-shaped plate 13 slides to the left on the lifting rod 14. The lifting rod 14 rises and then falls on the grooved plate 11, thus allowing the brush 12 to move with the grooved plate. The groove of the slot plate 11 moves, allowing the brush 12 to be immersed into the coloring cylinder 16 for coloring. Then, the fourth motor 39 drives the sliding rod 15 to rotate clockwise, causing the brush 12 to leave the coloring cylinder 16 and move downwards, so that the brush 12 comes into contact with the glass product. The first motor 4 and the second motor 6 are used to move the brush 12 to perform the coloring work, thus achieving an automatic coloring effect on the glass product, thereby eliminating the need for manual coloring, increasing efficiency, and making it less likely for personnel to get paint on their bodies.

[0051] In this embodiment, as Figure 1 , Figure 3 , Figure 8 As shown, the first slider 10 is slidably connected to both the front and rear ends of the left side of the frame 17 via grooves, and the second slider 23 is slidably connected to both the front and rear ends of the right side of the frame 17 via grooves. A sliding rod 19 is fixedly connected to the upper end of both the first slider 10 and the second slider 23. Threaded blocks 20 are fixedly connected to both sides of the sliding rod 19. A bidirectional threaded rod 18 is threadedly connected to the lower end of the threaded block 20. The left and right ends of the bidirectional threaded rod 18 are rotatably connected to the first slider 10 and the second slider 23, respectively. A suction cup 21 is provided at the upper end of the threaded block 20. An air suction pipe 22 is connected to the lower end of the suction cup 21. An air pump 44 is connected to the lower end of the air suction pipe 22. 44 is fixedly connected to the workbench 1 at its lower end; a worm gear 24 is sleeved and fixedly connected to the right end of the bidirectional threaded rod 18; a worm 25 is rotatably connected to the right end of the second slider 23; a grooved cylinder 26 and a protruding rod 40 are respectively connected to the ends of the worms 25 on the front and rear sides that are close to each other; the protruding rod 40 is inserted into the grooved cylinder 26; and the worm 25 and the worm gear 24 mesh with each other; a connecting rod 7 is rotatably connected to the left end of the first slider 10 through a pin; a threaded slider 9 is rotatably connected to the end of the connecting rod 7 away from the first slider 10 through a pin; a second threaded rod 8 is threadedly connected to the middle of the threaded slider 9; and the lower end of the second threaded rod 8 is rotatably connected to the frame 17.

[0052] In use, according to the size of the glass product, the operator manually rotates the second threaded rod 8 to drive the threaded slider 9 to rise and fall. Under the action of the connecting rod 7, the first sliders 10 on the front and rear sides slide simultaneously in opposite directions, adjusting the distance between the first sliders 10. At the same time, the protrusion rod 40 and the grooved cylinder 26 slide relative to each other. Then, the operator manually rotates the handle of the front worm gear 25 to make the worm wheel 24, the grooved cylinder 26, and the protrusion rod 40 rotate, causing the bidirectional threaded rod 18 to rotate. This causes the threaded blocks 20 on the left and right sides to move closer or further apart, so that the upper end of the suction cup 21 is in contact with the four corners of the glass product. Then, using the air pump 44, the suction cup 21 can be used to adsorb and position the glass product, thus achieving a positioning effect for glass products of different sizes, thereby ensuring the stability of the glass product during the coloring process and preventing it from shifting.

[0053] In this embodiment, as Figure 1 , Figure 4 , Figure 7 As shown, the hot air blower 43 has a hot air pipe 27 connected to its outlet end. A drying pipe 28 is connected to the front end of the hot air pipe 27. An air outlet nozzle is installed at the lower end of the drying pipe 28. Sliding columns 35 are fixedly connected to both the upper and lower sides of the right end face of the drying pipe 28. A displacement column 29 is slidably connected to the sliding column 35. A rectangular block 37 is fixedly connected to the right end face of the sliding column 35. A second sliding groove plate 31 is slidably connected to the lower end of the displacement column 29. A third motor 30 is fixedly connected to the rear end face of the second sliding groove plate 31. The output end of the third motor 30 is fixedly connected to... A third threaded rod 32 is fixedly connected to the displacement column 29. The lower end face of the second slide plate 31 is fixedly connected to the worktable 1. A spring 36 is sleeved on the right end of the upper slide column 35. The left end of the spring 36 is fixedly connected to the displacement column 29. The right end of the spring 36 is fixedly connected to the rectangular block 37. An eccentric block 38 and a gear 34 are rotatably connected to the right side of the displacement column 29 through a pin. A rack 33 is fixedly connected to the right side of the upper end face of the worktable 1. The rack 33 and the gear 34 mesh with each other.

[0054] In use, after coloring is completed, personnel can simultaneously start the third motor 30 and the hot air blower 43. The hot air blower 43 delivers hot air through the hot air pipe 27 to the drying pipe 28 and blows it onto the glass products from the nozzle. With the forward and backward movement of the displacement column 29, the drying range in the front and back directions is expanded. At the same time, under the action of the gear 34, the eccentric block 38 rotates continuously. The eccentric block 38 continuously squeezes the rectangular block 37, causing the sliding column 35 to slide and return to its original position under the action of the spring 36, causing the drying pipe 28 to move left and right, expanding the drying range in the left and right directions until the glass products are dried. This can achieve an automatic and uniform drying effect on the colored glass products, making it easier for personnel to collect them quickly.

[0055] A coloring method for a glass product coloring apparatus includes the following specific steps:

[0056] S1. According to the size of the glass product, the operator manually rotates the second threaded rod 8 to drive the threaded slider 9 to rise and fall. Under the action of the connecting rod 7, the first sliders 10 on the front and rear sides slide in opposite directions at the same time, adjusting the distance between the first sliders 10. At the same time, the protrusion rod 40 and the grooved cylinder 26 slide relative to each other. Then, the operator manually rotates the handle of the front worm gear 25 to make the worm wheel 24, the grooved cylinder 26, and the protrusion rod 40 rotate, causing the bidirectional threaded rod 18 to rotate, making the threaded blocks 20 on the left and right sides move closer or further away from each other, so that the upper end of the suction cup 21 just contacts the four corners of the glass product. Then, the air pump 44 is used to make the suction cup 21 adsorb and position the glass product.

[0057] S2. When it is time to start coloring the glass product, start the first motor 4 to drive the first threaded rod 3 to rotate, so that the L-shaped column 5 moves left and right. Start the second motor 6 to drive the fourth threaded rod 42 to rotate, so that the groove plate 11 moves back and forth, thereby adjusting the position of the brush 12. Then start the fourth motor 39 to drive the sliding rod 15 to rotate counterclockwise, so that the guide column 41 moves from right to left. The L-shaped plate 13 slides to the left on the lifting rod 14. The lifting rod 14 rises and then falls on the groove plate 11, so that the brush 12 moves along the groove trajectory of the groove plate 11, so that the brush 12 is immersed into the coloring cylinder 16 for coloring. Then start the fourth motor 39 to drive the sliding rod 15 to rotate clockwise again, so that the brush 12 leaves the coloring cylinder 16 and moves downward, so that the brush 12 contacts the glass product. The first motor 4 and the second motor 6 are used to move the brush 12 for coloring.

[0058] S3. After coloring is completed, the operator can simultaneously start the third motor 30 and the hot air blower 43. The hot air blower 43 delivers hot air to the drying tube 28 through the hot air pipe 27 and blows it onto the glass products from the nozzle. With the forward and backward movement of the displacement column 29, the drying range in the front and back directions is expanded. At the same time, under the action of the gear 34, the eccentric block 38 rotates continuously. The eccentric block 38 continuously squeezes the rectangular block 37, causing the sliding column 35 to slide and return to its original position under the action of the spring 36, so that the drying tube 28 moves left and right, expanding the drying range in the left and right directions until the glass products are dried.

[0059] S4. Finally, remove the glassware.

[0060] Working principle of this invention: In use, according to the size of the glass product, the operator manually rotates the second threaded rod 8 to drive the threaded slider 9 to rise and fall. Under the action of the connecting rod 7, the first sliders 10 on both the front and rear sides slide simultaneously in opposite directions, adjusting the distance between the first sliders 10. At the same time, the protrusion rod 40 and the grooved cylinder 26 slide relative to each other. Then, the operator manually rotates the handle of the front worm gear 25 to rotate the worm wheel 24, the grooved cylinder 26, and the protrusion rod 40, causing the bidirectional threaded rod 18 to rotate, making the threaded blocks 20 on the left and right sides move closer or further apart, thus facilitating suction. The upper end of the suction cup 21 contacts the four corners of the glass product. Then, using the air pump 44, the suction cup 21 can adsorb and position the glass product. When it's time to start coloring the glass product, the first motor 4 is started, driving the first threaded rod 3 to rotate, causing the L-shaped column 5 to move left and right. The second motor 6 is started, driving the fourth threaded rod 42 to rotate, causing the grooved plate 11 to move back and forth, thus adjusting the position of the brush 12. Then, the fourth motor 39 is started, driving the sliding rod 15 to rotate counterclockwise, causing the guide column 41 to move from right to left. The L-shaped plate 13 is positioned on the lifting rod 1. 4. Slide the lifting rod 14 to the left. The lifting rod 14 rises and then falls on the groove plate 11, allowing the brush 12 to move along the groove trajectory of the groove plate 11. This allows the brush 12 to be immersed into the coloring cylinder 16 for coloring. Then, the fourth motor 39 drives the sliding rod 15 to rotate clockwise, causing the brush 12 to leave the coloring cylinder 16 and move downwards, bringing the brush 12 into contact with the glass product. The first motor 4 and the second motor 6 are used to move the brush 12 for coloring. After coloring is completed, the third motor 30 and the heat exchanger can be started simultaneously. The blower 43 and the hot air blower 43 deliver hot air through the hot air pipe 27 to the drying pipe 28 and blow it onto the glass products from the nozzle. With the forward and backward movement of the displacement column 29, the drying range in the front and back directions is expanded. At the same time, under the action of the gear 34, the eccentric block 38 rotates continuously. The eccentric block 38 continuously squeezes the rectangular block 37, causing the sliding column 35 to slide and return to its original position under the action of the spring 36, so that the drying pipe 28 moves left and right, expanding the drying range in the left and right directions until the glass products are dried. Finally, the glass products can be removed.

[0061] Example 2

[0062] In actual use, operators found that when clamping glass of different shapes using this device, the center of gravity of the glass of different shapes could not be determined. As a result, the multiple suction cups 21 deformed to varying degrees due to the weight of the glass itself when clamping it, causing the glass to tilt in the direction of greater gravity. If the glass is colored by the brush 12 at this time, the liquid colorant will flow along the tilt direction, resulting in uneven coloring of the glass. When the coloring cylinder 16 is left for a long time, the colorant inside will precipitate, affecting the coloring effect. Therefore, in order to solve the above technical problems, the device was improved according to the method described in this embodiment.

[0063] Each air outlet nozzle on the drying tube 28 is equipped with a distance sensor on one side. The distance sensor is used to detect the distance between each air outlet nozzle and the glass. An air bag ring 45 is sleeved on the outside of the coloring tube 16. The air bag ring 45 is connected to the groove plate 11 by a connecting rod. The groove plate 11 is provided with ventilation holes near the coloring tube 16. A solenoid valve is provided inside the air outlet nozzle.

[0064] First, when the glass needs to be clamped, the second threaded rod 8 is rotated according to the shape and size of the glass, so that the threaded slider 9 drives the two first sliders 10 to move through the two connecting rods 7, thereby adjusting the distance between the front and rear sets of suction cups 21. Then, the worm gear 25 is controlled to drive the worm wheel 24 to rotate, adjusting the distance between the left and right sets of suction cups 21, so that multiple suction cups 21 move to the bottom of the glass and clamp the glass. Then, the third motor 30 is controlled to rotate, and with the cooperation of the gear 34 and the eccentric block 38, the drying tube 28 moves on the glass. At the same time, the hot air sprayed by the hot air blower 43 effectively cleans the upper surface of the glass, avoiding the problem of unsatisfactory glass coloring effect due to a large number of impurities covering the upper surface during the coloring process.

[0065] Secondly, when the drying tube 28 moves above the glass to clean debris, a distance sensor located on one side of each air outlet detects the distance between the glass and each air outlet in real time, records and analyzes the detection results, and thus determines the specific angle at which the glass tilts to one side, thereby determining the tilt status of the glass. When the brush 12 applies color to the glass, based on the obtained glass tilt status, the fourth motor 39 is controlled to drive the sliding rod 15 to rotate, causing the guide post 41 on the sliding rod 15 to slide up and down within the groove on the groove plate 11. This ensures that the distance between the brush 12 and the glass remains consistent. That is, if one side of the glass is higher than the horizontal plane, the fourth motor 39 is controlled to drive the brush 12 to move upward; if one side of the glass is lower than the horizontal plane, the fourth motor 39 is controlled to drive the brush 12 to move downward. This ensures that the thickness of the colorant applied by the brush 12 to all parts of the tilted glass remains consistent, effectively solving the problem of uneven colorant thickness on different parts of the glass due to the glass tilt.

[0066] Furthermore, while the brush 12 is coloring the glass, the drying tube 28 is moved synchronously on the glass by controlling the third motor 30. Simultaneously, the airflow of the hot air blower 43 is adjusted according to the up-and-down movement of the brush 12, ensuring that the hot air from the drying tube 28 dries the colorant on the glass promptly. This prevents the colorant from failing to solidify quickly on the tilted glass due to insufficient drying force, or from passively flowing due to excessive drying force caused by the wind. This further improves the coloring effect of the device. Simultaneously, a distance sensor installed on the drying tube 28 monitors the thickness of the glass coloring layer in real time. If the coloring layer thickness remains within a preset range, it indicates that the amount of colorant adsorbed on the brush 12 is within the preset range; if the thickness is greater than the preset range, the thickness is not monitored. If the thickness of the coloring layer is less than the preset range, it indicates that the amount of colorant adsorbed on the brush 12 is too large. In this case, the fourth motor 39 is controlled to drive the guide column 41 to move the brush 12 above the coloring cylinder 16. The fourth motor 39 then drives the brush 12 to reciprocate and shake, throwing the excess colorant into the coloring cylinder 16, thus preventing the problem of excessive colorant on the brush 12 affecting the coloring effect. Conversely, if the thickness of the coloring layer is less than the preset range, it indicates that the amount of colorant adsorbed on the brush 12 is too small. It also indicates that the water level of the colorant in the coloring cylinder 16 has dropped after long-term use. In this case, the amount of water level drop in the coloring cylinder 16 is judged based on the thickness of the coloring layer, and the fourth motor 39 is controlled to drive the brush 12 to move into the coloring cylinder 16, so that the amount of colorant on the brush 12 is always within the preset range, further improving the coloring effect on the glass.

[0067] Finally, to prevent the colorant in the coloring cylinder 16 from settling after a long period of time, when the first motor 4 drives the coloring cylinder 16 and the brush 12 to move left and right on the glass, a distance sensor installed on the drying tube 28 detects the thickness of the brush 12 and the glass in real time. If the displacement sensor at a certain point detects a distance value that is much greater than the preset range, it means that the distance sensor at that point is at the glass boundary. When the drying tube 28 moves, it causes the distance sensor at that point to be misaligned with the glass. The size of the glass is determined based on the detection result. When the first motor 4 drives the coloring cylinder 16 to move diagonally above the glass, the hot air blower 43 is controlled to introduce heat into the drying tube 28. The air volume is increased, and the air outlet nozzle directly above the glass is closed, causing the air outlet nozzle opposite the coloring cylinder 16 to spray high-temperature gas. As the hot gas flows upward and comes into contact with the coloring cylinder 16, it keeps the colorant inside the coloring cylinder 16 warm, preventing the colorant from solidifying. At the same time, the hot gas causes the air bladder ring 45 outside the coloring cylinder 16 to expand. When the coloring cylinder 16 moves above the glass, the drying tube 28 returns to normal operation. At this time, the hot gas received by the air bladder ring 45 will decrease, and the gas inside the air bladder will contract. During this process, the air bladder ring 45 will cause the coloring cylinder 16 to shake, effectively preventing the colorant inside the coloring cylinder 16 from settling after a long period of time.

[0068] It should be noted that this invention, by setting multiple distance sensors on the drying tube 28, records the tilt of the glass when the drying tube 28 is cleaning dust from the glass. This allows the brush 12 to adjust its distance from the glass according to the tilt, thus avoiding uneven thickness of the coloring layer caused by the glass's tilt. Simultaneously, the hot air volume of the drying tube 28 is adjusted according to the glass's tilt, preventing uneven coloring layer thickness due to excessive or insufficient drying force. Furthermore, the distance sensors detect dimensions that allow the drying tube 28 to change its airflow during movement, preventing the colorant in the coloring cylinder 16 from settling and affecting the coloring effect.

[0069] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.

According to the size of the glass product, the operator manually rotates the second threaded rod to drive the threaded slider to rise and fall. Under the action of the connecting rod, the first sliders on the front and rear sides slide in opposite directions at the same time, adjusting the distance between the first sliders. At the same time, the protrusion rod and the grooved cylinder slide relative to each other. Then, the operator manually rotates the handle of the front worm gear to make the worm wheel, grooved cylinder, and protrusion rod rotate, causing the bidirectional threaded rod to rotate, making the threaded blocks on the left and right sides move closer or further apart, so that the upper end of the suction cup just contacts the four corners of the glass product.

Start the second motor to drive the fourth threaded rod to rotate, so that the groove plate moves back and forth, thereby adjusting the position of the brush. Then start the fourth motor to drive the sliding rod to rotate counterclockwise, so that the guide column moves from right to left. The L-shaped plate slides to the left on the lifting rod. The lifting rod rises and then falls on the groove plate, so that the brush moves along the groove trajectory of the groove plate and is immersed into the coloring cylinder for coloring.
